Heavy Snow — Yavapai County Mountains, Arizona

2022-02-22 to 2022-02-23 · Yavapai County Mountains, Arizona

Event narrative

Heavy snow fell across Yavapai County including 8.5 inches in Ash Fork, 8 inches in Ponderosa Park, and 4.0-6 inches across the Prescott area.

Wider weather episode

A large trough of low pressure brought increasing moisture off from off the eastern Pacific marine layer over central Arizona. This brought extensive upslope snow shower activity coverage, especially along and White Mountains. The trough brought very cold air across Arizona (down to -12C at 700 mb) with saturation to at least 500 mb. This made for a very efficient snow process with significant, widespread accumulations.
